Use Of Psychological Skills By Risk Sport Athletes, Patrick R. Young, Erin L. Knight

Journal of Human Performance in Extreme Environments

Psychological skills can help athletes maximize their physical skills (Smith, Schutz, Smoll, & Ptacek, 1995) and overcome sport-related adversity. These skills may be especially beneficial to athletes performing within natural and unstable risk sport environments. The current study assessed psychological skills among risk sport athletes (N = 232) and the impact of experience on the use of such skills. Risk sport athletes of varying degrees of experience completed a modified version of the Athletic Coping Skills Inventory (ACSI; Smith et al., 1995). Risk sport athletes exceeded the midpoint on all of the ACSI subscales, indicating psychological skills usage. Experienced …

High And Low Computer Self-Efficacy Groups And Their Learning Behavior From Self-Regulated Learning Perspective While Engaged In Interactive Learning Modules, Harry B. Santoso, Oenardi Lawanto, Kurt Becker, Ning Fang, Edward M. Reeve

Journal of Pre-College Engineering Education Research (J-PEER)

The purpose of this research was to investigate high school students’ computer self-efficacy (CSE) and learning behavior in a selfregulated learning (SRL) framework while utilizing an interactive learning module. The researcher hypothesizes that CSE is reflected on cognitive actions and metacognitive strategies while the students are engaged with interactive learning modules. Two research questions guided this research: (1) how is students’ CSE while engaged in interactive learning modules? and (2) how do high and low CSE groups plan and monitor their cognitive action, and regulate their monitoring strategies based on their CSE level? The research used a mixedmethods approach to …

Role Of Group Ii Metabotropic Glutamate Receptor Subtype 2 (Mglur2) In Appetitive And Consummatory Aspects Of Ethanol Reinforcement, Kyle Allyson Windisch

Open Access Dissertations

Background: Group II metabotropic glutamate receptors (mGluR2/3) are predominately presynaptically located G_i/o coupled receptors that are highly expressed in the cortex, nucleus accumbens, amygdala, and hippocampus. Previous studies suggest that group II mGluRs are involved in regulating ethanol (EtOH) consumption and seeking following extinction (Backstrom and Hyytia, 2005; Kufahl, et al., 2011). The sipper tube model, which allows for procedural separation of seeking and consumption, was used to further clarify the role of mGluR2/3 in EtOH-seeking and consumption. The non-selective group II mGluR agonist LY379268 (LY37) and selective mGluR2 positive allosteric modulator (PAM) BINA were used to determine the …

Customer Envy At Service Encounters, Gerardo Anaya

Open Access Theses

Envy has been regarded as a complex emotion which can produce both positive and negative outcomes for consumers. This study explored the subjective experience of customer envy at service encounters in order to better understand how customers respond to unflattering comparisons with an envied customer. A questionnaire was designed to measure the cognitive appraisals, emotional responses, and consequences of customer envy. Study participants were also asked to share their envy incidents in the survey. A sample of 300 participants was collected and used for analysis. The findings illustrate that distinctively different patterns of cognitive appraisals such as preferential treatment, are …

The Impact Of An Omega-3 Enriched Diet On Hyperactivity And Biochemistry In An Animal Model For Attention-Deficit/Hyperactivity Disorder, Nadine M. Hammoud

Open Access Theses

Attention-deficit/hyperactivity disorder (ADHD) is the most diagnosed behavioral disorder in children. It affects around 5% of children worldwide and 11% of children in the United States, with rates increasing. Pharmaceutical treatments, such as amphetamines and methylphenidates, are not effective for everyone and are known to have unwanted side effects. While the etiology of the disorder is not yet fully understood, there are clear genetic and environmental components. Nutritional insufficiencies have recently become a popular environmental risk factor under investigation. Essential fatty acids (EFA), omega-3 polyunsaturated fatty acids (PUFA) in particular, are needed for proper brain development and function. Our lab …

Open Access Theses

ABSTRACT Harris, Rachel C. M. S., Purdue University, December 2014. Postural Control in Infants at Low and High Risk for Autism Spectrum Disorder. Major Professor: Laura J. Claxton. Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder more commonly known for deficits in social and communication skills. More recently, aspects of motor development have been shown to be delayed in children with ASD, including deficits in their postural control abilities. Children with ASD have difficulty integrating information from their sensory systems to help control their balance. Infants at risk for ASD and infants who are later diagnosed with ASD have delays …

Multidimensional Approach To Comparative Avian Visual Systems, Bret Alan Moore

Open Access Dissertations

Since the birth of visual ecology, comparative studies on how birds see their world have been limited to a small number of species and tended to focus on a single visual trait. This approach has constrained our ability to understand the diversity and evolution of the avian visual system. The goal of this dissertation was to characterize multiple visual dimensions on bird groups that are highly speciouse (e.g., Passeriformes), and test some hypotheses and predictions, using modern comparative tools, on the relationship between different visual traits and their association with visual information sampling behaviors. First, I developed a novel method …

Acquisition, Retention And Transfer Of Heavy Equipment Operator Skills Through Simulator Training, Chung Yin So

Open Access Dissertations

Initiatives and collaborations among heavy construction equipment manufacturing companies and training technology firms to develop and employ simulators for varied training purposes are becoming commonplace. However, human factors research on simulator training for operators of construction equipment is still sparse. For simulator training to be effective, it is necessary to understand how skills are learned using the simulator, how those skills are transferred to other tasks, devices, and real scenarios, and how well skills are retained after simulator training. ^ This research is on skill development, specifically as it applies to operator training for two specific types of heavy construction …

Capacity-Related Driver Behavior On Modern Roundabouts Built On High-Speed Roads, Shaikh Ahmad

Open Access Theses

The objective of this thesis was to investigate the factors that affect capacity-related driver behavior on modern roundabouts built on high-speed roads. The capacity of roundabouts is strongly affected by the behavior of drivers as represented by critical headway (critical gap) and follow-up headway (follow-up time). The effects of heavy vehicles (single-unit truck, bus, and semi-trailer) and area type (rural or urban) on roundabout capacity were investigated by comparing the critical headways for roundabouts located on high-speed and low-speed roads. The effects of nighttime conditions (in the presence of street lighting) were also considered. Data were collected using the Purdue …

Optimization Of Switch Virtual Keyboard By Using Computational Modelling, Xiao Zhang

Open Access Theses

In this thesis, I first reviewed some keyboard technologies used by people with motor difficulties, and described design elements that influence efficiency. I cast the design of a switch keyboard as an optimization problem, and arrangement of keys on such a keyboard as a Mixed Integer Programming problem. One significant variable in the MIP problem, the error rate, is related to several other variables. I treated modeling of the error rate as a parameter estimation problem, and used a data mining method. I designed HCI experiments to gather data for parameter estimation, using Bayesian logistic regression model. The empirical data …

Increasing Participation In The Pilot Weather Reporting (Pirep) System Through User Interface Design, Stephen M. Casner

Journal of Aviation Technology and Engineering

Although pilots regard pilot weather reports (PIREPs) as valuable flight planning resources, the number of PIREPs that pilots submit is relatively small. In a previous survey, pilots indicated that submitting PIREPs sometimes requires too much effort, and that they are often unable to recall the information fields required to complete a report. Pilots also indicated that the idea of submitting a PIREP often does not occur to them, and that they feel that other pilots are mainly interested in receiving reports about severe weather. In this study the authors attempt to address obstacles to submitting PIREPs by proposing two alternative …

Reduced Intestinal Brain-Derived Neurotrophic Factor Increases Vagal Sensory Innervation Of The Intestine And Enhances Satiation, Jessica E. Biddinger, Edward A. Fox

Department of Psychological Sciences Faculty Publications

Brain-derived neurotrophic factor (BDNF) is produced by developing and mature gastrointestinal (GI) tissues that are heavily innervated by autonomic neurons and may therefore control their development or function. To begin investigating this hypothesis, we compared the morphology, distribution, and density of intraganglionic laminar endings (IGLEs), the predominant vagal GI afferent, in mice with reduced intestinal BDNF (INT-BDNF_/_) and controls. Contrary to expectations of reduced development, IGLE density and longitudinal axon bundle number in the intestine of INT-BDNF_/_ mice were increased, but stomach IGLEs were normal. INT-BDNF_/_ mice also exhibited increased vagal sensory neuron numbers, suggesting that their survival was enhanced. …

The Parkinson's Experience Of Group Physical Activity: Understanding Social Support, Social Comparison, Physical Self-Perceptions, And Posttraumatic Growth, Tammy L. Sheehy

Open Access Theses

Group physical activity programs for clinical populations can provide opportunities for adaptive social interactions, improving perceptions of competence, and may facilitate posttraumatic growth (positive psychological changes resulting from traumatic life experiences). Therefore, the purpose of this study was to examine how people with Parkinson's experience social interactions and physical challenges in a group physical activity program, and to investigate what role they think those experiences play in posttraumatic growth. The study employed interpretative phenomenological analysis methodology (Smith, Flowers & Larkin, 2009). N= 20 participants ( n = 12 women; age = 56-79 years) in a boxing-based group exercise program …

Dismantling The Great Wall Of Prejudice: A Look At Centrality And Issue Importance In The Perpetuation Of Influence And Prejudice Reduction, Zachary Robert Wittrock

Open Access Theses

This study sought to utilize social network analysis to better understand how prejudice reduction can be spread from one person to another via interpersonal influence. Different types of prejudice reducing interventions were combined into one intervention. The role of centrality in the spread and perpetuation of influence was examined by measuring prejudice reduction in socially connected individuals who did not undergo the direct intervention. To further understand the role of centrality in prejudice reduction, the concept of issue importance was included to understand the differential impact that centrality has on interpersonal influence. Study 1 examined the effectiveness of the intervention, …

The Nature Of Parental Involvement In Middle School: Examining Nonlinear Associations, Elizabeth A. Wehrspann

Open Access Theses

Middle school is a time during which the importance of school performance and academic motivation increases, yet actual adolescent achievement and motivation tend to decline during this period. Extent research and theory highlight the importance of parental involvement in education for adolescents, as most work shows that parent involvement is positively related to academic achievement and motivation. However, there are also many mixed findings regarding the link between specific types of involvement (i.e., home-based involvement and academic socialization) and these outcomes. Further, little work has been done to examine the possible age-related differences in these associations. Guided by Self-Determination Theory …

Is Maternal Touch Used Referentially?, Rana Abu-Zhaya

Open Access Theses

Early social interactions are highly multimodal and include a wealth of cues (e.g., speech, facial expressions, motion, gestures and touch). Infant-directed speech (IDS) by itself may aid in language development. Touch by itself has been also shown to play an important role in dyadic interactions affecting both the infant and the caregiver. However, little is known about the impact of the combination of these two modes of communication on infant language development. In this thesis, I hypothesize that caregiver touch is provided in synchrony with speech, providing the language-learning infant with cues that may not only help her to find …

The Effect Of Ostracism By Strangers On Romantic Relationship Evaluations, Maayan Dvir

Open Access Theses

One behavioral consequence of ostracism is to seek and strengthen connections with others. The current research tests whether a brief episode of ostracism by strangers strengthens targeted individuals' perceptions of their romantic relationship and increases their desire to be closer to their partner. In Study 1a and Study 1b, participants were either included or ostracized by strangers in a Cyberball game, and then completed relationship evaluation measures. Interactions of ostracism and gender emerged, suggesting that as hypothesized, ostracized women tended to evaluate their relationships more positively than included women. However, men who were ostracized tended to evaluate their relationships less …

Preschoolers’ Physical, Social, And Engineering Play Behaviors: Differences In Gender And Play Environment, Zachary S. Gold

Open Access Theses

This study explored gender differences in the occurrence of 66 preschoolers' (ages 3-to-5; 29 girls, 37 boys) physical, social, and "engineering thinking play" behaviors across three play environments: the traditional playground, the dramatic play area, and an environment in which children played with large, manipulable, loose parts. Previous research has indicated that young children are not engaging in enough physical play to maintain healthy lifestyles. Play may also have benefits for social competency and cognitive development. Observations of children's engagement with a new and engaging play material, Imagination Playground TM blocks, which are designed to foster imaginative and creative constructive …

Perceptual Compensation In Individuals With Autism Spectrum Disorders, Elizabeth Anne Langston

Open Access Theses

Compensation for coarticulation is the extent in which an individual perceives the contextual variations of speech. When presented with an ambiguous consonant-vowel segment (e.g., a consonant halfway between /sa/ and /∫a/) research illustrates that a listener is likely to compensate for coarticulation with the following vowel. Therefore, a listener will be more likely to report an ambiguous speech sound as /s/ when it occurs before [u] than before [a]. Previous results have suggested that, within neurotypical individuals, the degree to which individuals compensate for coarticulation may be related to their Autism Quotient (AQ; Yu, 2010). However, this research did not …

Habitat Effects On Chick-A-Dee Call Complexity, Jacqueline Renee Lynch

Open Access Theses

Past studies on the communication systems of species in urban environments (such as Common Starlings (Sturnus vulgaris), nightingales (Luscinia megarhynchos Brehm), brown-headed cowbirds ( Molothrus ater), Southern brown tree frogs (Litoria ewingii )) have shown multiple ways that species change vocal signaling behavior to adjust to urban habitats (e.g. alarm calls and singing). This study further investigates the changes in signaling in relation to the chick-a-dee call of the Carolina chickadee (Poecile carolinensis). A secondary goal of this study was to compare both the amount of information and rate of calling across …

Human And Canine Personality Assessment Instruments To Predict Successful Adoptions With Shelter Dogs, Sheryl Lynn Walker

Open Access Dissertations

Animal shelters are often over-crowded with animals, and efforts to match potential adopters with shelter dogs, to improve the quality of adoptions, are increasing. However, a lack of evidence-based practices makes matching difficult. This research was conducted to investigate the role of dog and human personality, using questionnaire-based measurements, on adoption success in two Indiana shelters, Clinton County Humane Society and the Humane Society of Indianapolis. Ultimately, the aim of this project was to assess dog personality, human personality, and satisfaction, to evaluate adoption success in shelter dogs.^ The present thesis contains three studies exploring dog and human personality traits, …

Influence Of Referential Coding In A Choice Task Performed In A Simulated Driving Cockpit, Aiping Xiong

Open Access Theses

Driving and other tasks performed by the driver of a vehicle are spatial. Thus, it is important to understand how the driver represents the spatial environment. In laboratory studies, the Simon task is used to study spatial coding. Participants are to make a left or right response to a nonspatial stimulus feature, but the stimulus can occur in a left or right position. The Simon effect is that responses are faster when the stimulus location corresponds with the response location. That effect is not usually found for a go/no-go task in which only one response is made to one of …

Relations Between Teachers’ Motivation And Students’ Motivation: A Self-Determination Theory Perspective, Inok Ahn

Open Access Theses

There is little research that examines impact teachers' motivation on students' motivation due to sparse attention to teachers' motivation. The primary purpose of this study was to investigate the relations between teachers' motivation and students' motivation using self-determination theory. Participants were 697 5th and 6th students and 35 of their teachers in Seoul, South Korea. Students completed the questionnaires for motivation, basic psychological needs, and perceptions of teacher's instructional styles. Teachers also answered questionnaires about their own motivation. Multiple regression analyses were used to analyze the data. Teaching experience was controlled for throughout the analysis process due to its significant …

Stress And Coping As A Function Of Experience Level In Collegiate Flight Students, Jennifer Kirschner, John Young, Richard Fanjoy

Journal of Aviation Technology and Engineering

Aviation as an industry requires a high degree of precision at all times. Large amounts of stress have been known to decrease performance to undesirable levels. While stress reactions and the coping skills used after encountering stressful situations differ from person to person, generalities can be made by comparing differences between groups. A large number of pilot applicants receive initial training within a university flight program each year. In order to better understand the perceived stress level and the coping skills used by these students, the current research project administered a perceived stress test and a coping skills inventory to …

Attachment Representations And Mother-Child Dialogue, Baiba Barene

Open Access Theses

With the emerging linguistic competencies of the child, dialogue becomes a regular part of mother-child everyday interactions, and may serve as one of the mechanisms of transmission of attachment in early and middle childhood. The goal of this study was to investigate the hypothesis about the co-constructive nature of children's knowledge of secure base script. Formation of the secure base script is a result of child-caregiver interactions that have been consolidated into a unit of knowledge available for use in attachment related situations. Individual attachment narratives and mother-child co-constructed narratives were collected from 86 mother-child dyads when children were 3.7 …

Social media transformed the process of crisis communication. This technology enables the user to communicate with emergency officials as well as the whole virtual world in a click of a button. The emergence of social media in emergency management and its role in raising situational awareness is growing tremendously, making it important for emergency officials to better understand the users' needs and perceptions.

This study's goal is to gain a better understanding of the expectations and perceptions that Purdue associates have regarding the use of social media as it relates to emergencies. The set of interviews conducted in this study …

Ostracism And Interest In Extreme Groups, Andrew H. Hales

Open Access Theses

Drawing from the temporal need-threat theory of ostracism (Williams, 2009), and uncertainty-identity theory (Hogg, 2007), I tested the hypothesis that ostracism increases interest in extreme groups. In a cross-sectional survey, Study 1 showed that chronic ostracism positively predicts interest in the Westboro Baptist Church, Mormonism, Scientology, and Alcoholics Anonymous. Study 2 established causal direction; relative to included participants, ostracized participants expressed greater willingness to attend a meeting of an extreme group following a recruitment attempt. Expressing a desire to attend meetings facilitated recovery of basic need satisfaction. Ostracism also induced self-uncertainty, but this did not mediate the effect. In an …

Gap Between Hospitality Employers' Demands And Hospitality Students' Perceptions Regarding Entry-Level Managers' Requirements In The United States, Yijun Huang

Open Access Theses

This study aims to identify the gap between recruiters and students regarding what knowledge, skills and abilities are most needed for graduates to secure entry-level managers in the hospitality industry. Previous literature used different approaches to attain a similar idea that students and recruiters do have different opinions, especially for those intrinsic or person-related characteristics. The researcher borrowed statements from different researchers and added two statements to make up the missing part of previous research and then combined, split and revised these statements to see whether students' thinking matched the industry's thinking. The results showed that recruiters generally ranked these …

Anticipatory And Reactive Responses To Chocolate Restriction In Frequent Chocolate Consumers, Chelsey L. Keeler

Open Access Theses

Many individuals have difficulty adhering to a weight loss diet. One possible explanation could be that dietary restriction paradoxically contributes to overconsumption. The objective of this study was to examine ingestive behavior under a forced chocolate restriction, with a focus on the anticipatory restriction period and the post-restriction period in frequent chocolate consumers. Fifty-six male (N=18) and female (N=38) high chocolate consumers with high or low cognitive disinhibition aged 27.70 ± 11.09 years with a mean BMI of 25.68± 5.92 kg/m2 participated. Chocolate snacks were provided for the first, second, and sixth week of the study to establish baseline, pre-restriction …
